CocoPro Cubes contain thoroughly washed and buffered coco fiber, pith, and husk for a consistent ratio of air and water throughout each cube. This high-performance blend delivers oxygen to plant roots while retaining moisture and nutrients – giving you more control over your fertigation regimen. The breathable fabric cover promotes air/gas exchange for increased root-zone oxygen levels, provides excellent water drainage for faster dry-down times, and encourages natural pruning and branching for a healthy root system. CocoPro Cubes come with a custom blend of coco pith and fibers. Each cube features a pre-drilled indentation for easy planting and fast hydration. These compressed grow media blocks are made from high-quality, buffered coconut coir. The entire Cocopro line is designed to provide consistent quality while reducing the time and labor costs required to hand-fill pots.
